Detailed Description

Interface to driver which is able to perform 2d and 3d graphics functions.

This interface is one of the most important interfaces of the Irrlicht Engine: All rendering and texture manipulation is done with this interface. You are able to use the Irrlicht Engine by only invoking methods of this interface if you like to, although the irr::scene::ISceneManager interface provides a lot of powerful classes and methods to make the programmer's life easier.

Member Function Documentation

◆ addDynamicLight()

virtual s32 irr::video::IVideoDriver::addDynamicLight ( const SLight & light )

pure virtual

adds a dynamic light, returning an index to the light

Parameters

light the light data to use to create the light

Returns: An index to the light, or -1 if an error occurs

◆ addExternalImageLoader()

virtual void irr::video::IVideoDriver::addExternalImageLoader ( IImageLoader * loader )

pure virtual

Adds an external image loader to the engine.

This is useful if the Irrlicht Engine should be able to load textures of currently unsupported file formats (e.g. gif). The IImageLoader only needs to be implemented for loading this file format. A pointer to the implementation can be passed to the engine using this method.

Parameters

loader Pointer to the external loader created.

◆ addExternalImageWriter()

virtual void irr::video::IVideoDriver::addExternalImageWriter ( IImageWriter * writer )

pure virtual

Adds an external image writer to the engine.

This is useful if the Irrlicht Engine should be able to write textures of currently unsupported file formats (e.g .gif). The IImageWriter only needs to be implemented for writing this file format. A pointer to the implementation can be passed to the engine using this method.

Parameters

writer Pointer to the external writer created.

◆ addMaterialRenderer()

virtual s32 irr::video::IVideoDriver::addMaterialRenderer	(	IMaterialRenderer *	renderer,
		const c8 *	name = 0 )

pure virtual

Adds a new material renderer to the video device.

Use this method to extend the VideoDriver with new material types. To extend the engine using this method do the following: Derive a class from IMaterialRenderer and override the methods you need. For setting the right renderstates, you can try to get a pointer to the real rendering device using IVideoDriver::getExposedVideoData(). Add your class with IVideoDriver::addMaterialRenderer(). To use an object being displayed with your new material, set the MaterialType member of the SMaterial struct to the value returned by this method. If you simply want to create a new material using vertex and/or pixel shaders it would be easier to use the video::IGPUProgrammingServices interface which you can get using the getGPUProgrammingServices() method.

Parameters

renderer	A pointer to the new renderer.
name	Optional name for the material renderer entry.

Returns: The number of the material type which can be set in SMaterial::MaterialType to use the renderer. -1 is returned if an error occured. For example if you tried to add an material renderer to the software renderer or the null device, which do not accept material renderers.

◆ addOcclusionQuery()

virtual void irr::video::IVideoDriver::addOcclusionQuery	(	scene::ISceneNode *	node,
		const scene::IMesh *	mesh = 0 )

pure virtual

Create occlusion query.

Use node for identification and mesh for occlusion test.

◆ addRenderTargetTexture()

virtual ITexture * irr::video::IVideoDriver::addRenderTargetTexture	(	const core::dimension2d< u32 > &	size,
		const io::path &	name = "rt",
		const ECOLOR_FORMAT	format = ECF_UNKNOWN )

pure virtual

Adds a new render target texture to the texture cache.

Parameters

size	Size of the texture, in pixels. Width and height should be a power of two (e.g. 64, 128, 256, 512, ...) and it should not be bigger than the backbuffer, because it shares the zbuffer with the screen buffer.
name	An optional name for the RTT.
format	The color format of the render target. Floating point formats are supported.

Returns: Pointer to the created texture or 0 if the texture could not be created. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

◆ addTexture() [1/2]

virtual ITexture * irr::video::IVideoDriver::addTexture	(	const core::dimension2d< u32 > &	size,
		const io::path &	name,
		ECOLOR_FORMAT	format = ECF_A8R8G8B8 )

pure virtual

Creates an empty texture of specified size.

Parameters

size	Size of the texture.
name	A name for the texture. Later calls to getTexture() with this name will return this texture
format	Desired color format of the texture. Please note that the driver may choose to create the texture in another color format.

Returns: Pointer to the newly created texture. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

◆ addTexture() [2/2]

virtual ITexture * irr::video::IVideoDriver::addTexture	(	const io::path &	name,
		IImage *	image,
		void *	mipmapData = 0 )

pure virtual

Creates a texture from an IImage.

Parameters

name	A name for the texture. Later calls of getTexture() with this name will return this texture
image	Image the texture is created from.
mipmapData	Optional pointer to a set of images which build up the whole mipmap set. Must be images of the same color type as image. If this parameter is not given, the mipmaps are derived from image.

Returns: Pointer to the newly created texture. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

◆ beginScene()

virtual bool irr::video::IVideoDriver::beginScene	(	bool	backBuffer = true,
		bool	zBuffer = true,
		SColor	color = SColor(255, 0, 0, 0),
		const SExposedVideoData &	videoData = SExposedVideoData(),
		core::rect< s32 > *	sourceRect = 0 )

pure virtual

Applications must call this method before performing any rendering.

This method can clear the back- and the z-buffer.

Parameters

backBuffer	Specifies if the back buffer should be cleared, which means that the screen is filled with the color specified. If this parameter is false, the back buffer will not be cleared and the color parameter is ignored.
zBuffer	Specifies if the depth buffer (z buffer) should be cleared. It is not nesesarry to do so if only 2d drawing is used.
color	The color used for back buffer clearing
videoData	Handle of another window, if you want the bitmap to be displayed on another window. If this is an empty element, everything will be displayed in the default window. Note: This feature is not fully implemented for all devices.
sourceRect	Pointer to a rectangle defining the source rectangle of the area to be presented. Set to null to present everything. Note: not implemented in all devices.

Returns: False if failed.

◆ checkDriverReset()

virtual bool irr::video::IVideoDriver::checkDriverReset ( )

pure virtual

Check if the driver was recently reset.

For d3d devices you will need to recreate the RTTs if the driver was reset. Should be queried right after beginScene().

◆ clearZBuffer()

virtual void irr::video::IVideoDriver::clearZBuffer ( )

pure virtual

Clears the ZBuffer.

Note that you usually need not to call this method, as it is automatically done in IVideoDriver::beginScene() or IVideoDriver::setRenderTarget() if you enable zBuffer. But if you have to render some special things, you can clear the zbuffer during the rendering process with this method any time.

◆ convertColor()

virtual void irr::video::IVideoDriver::convertColor	(	const void *	sP,
		ECOLOR_FORMAT	sF,
		s32	sN,
		void *	dP,
		ECOLOR_FORMAT	dF ) const

pure virtual

Color conversion convenience function.

Convert an image (as array of pixels) from source to destination array, thereby converting the color format. The pixel size is determined by the color formats.

Parameters

sP	Pointer to source
sF	Color format of source
sN	Number of pixels to convert, both array must be large enough
dP	Pointer to destination
dF	Color format of destination

◆ createAttributesFromMaterial()

virtual io::IAttributes * irr::video::IVideoDriver::createAttributesFromMaterial	(	const video::SMaterial &	material,
		io::SAttributeReadWriteOptions *	options = 0 )

pure virtual

Creates material attributes list from a material.

This method is useful for serialization and more. Please note that the video driver will use the material renderer names from getMaterialRendererName() to write out the material type name, so they should be set before.

Parameters

material	The material to serialize.
options	Additional options which might influence the serialization.

Returns: The io::IAttributes container holding the material properties.

◆ createImage() [1/4]

◆ draw3DBox()

virtual void irr::video::IVideoDriver::draw3DBox	(	const core::aabbox3d< f32 > &	box,
		SColor	color = SColor(255, 255, 255, 255) )

pure virtual

Draws a 3d axis aligned box.

This method simply calls draw3DLine for the edges of the box. Note that the box is drawn using the current transformation matrix and material. So if you need to draw it independently of the current transformation, use

driver->setMaterial(someMaterial);

driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

irr::core::IdentityMatrix

IRRLICHT_API const matrix4 IdentityMatrix

global const identity matrix

irr::video::ETS_WORLD

@ ETS_WORLD

World transformation.

Definition IVideoDriver.h:61

for some properly set up material before drawing the box.

Parameters

box	The axis aligned box to draw
color	Color to use while drawing the box.

◆ draw3DLine()

virtual void irr::video::IVideoDriver::draw3DLine	(	const core::vector3df &	start,

		SColor	color = SColor(255, 255, 255, 255) )

pure virtual

Draws a 3d line.

For some implementations, this method simply calls drawVertexPrimitiveList for some triangles. Note that the line is drawn using the current transformation matrix and material. So if you need to draw the 3D line independently of the current transformation, use

driver->setMaterial(someMaterial);

driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

for some properly set up material before drawing the line. Some drivers support line thickness set in the material.

Parameters

start	Start of the 3d line.
end	End of the 3d line.
color	Color of the line.

◆ draw3DTriangle()

virtual void irr::video::IVideoDriver::draw3DTriangle	(	const core::triangle3df &	triangle,
		SColor	color = SColor(255, 255, 255, 255) )

pure virtual

Draws a 3d triangle.

This method calls drawVertexPrimitiveList for some triangles. This method works with all drivers because it simply calls drawVertexPrimitiveList, but it is hence not very fast. Note that the triangle is drawn using the current transformation matrix and material. So if you need to draw it independently of the current transformation, use

driver->setMaterial(someMaterial);

driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

for some properly set up material before drawing the triangle.

Parameters

triangle	The triangle to draw.

pure virtual

Sets a boolean alpha channel on the texture based on the color at a position.

This makes the texture fully transparent at the texels where the color key can be found when using for example draw2DImage with useAlphachannel==true. The alpha of other texels is not modified.

Parameters

texture	Texture whose alpha channel is modified.
colorKeyPixelPos	Position of a pixel with the color key color. Every texel with this color will become fully transparent as described above.
zeroTexels

Deprecated: If set to true, then any texels that match the color key will have their color, as well as their alpha, set to zero (i.e. black). This behavior matches the legacy (buggy) behavior prior to release 1.5 and is provided for backwards compatibility only. This parameter may be removed by Irrlicht 1.9.

◆ makeColorKeyTexture() [2/2]

virtual void irr::video::IVideoDriver::makeColorKeyTexture	(	video::ITexture *	texture,

Parameters

texture	Texture whose alpha channel is modified.
color	Color key color. Every texel with this color will become fully transparent as described above. Please note that the colors of a texture may be converted when loading it, so the color values may not be exactly the same in the engine and for example in picture edit programs. To avoid this problem, you could use the makeColorKeyTexture method, which takes the position of a pixel instead a color value.
zeroTexels

Deprecated: If set to true, then any texels that match the color key will have their color, as well as their alpha, set to zero (i.e. black). This behavior matches the legacy (buggy) behavior prior to release 1.5 and is provided for backwards compatibility only. This parameter may be removed by Irrlicht 1.9.

This method enables access to special color buffers such as stereoscopic buffers or auxiliary buffers.

Parameters

target	Enum value for the render target
clearTarget	Clears the target buffer with the color parameter

		video::ITexture *	depthStencil = 0 )

pure virtual

Sets a new render target. (this prototype will be removed in future).

This will only work if the driver supports the EVDF_RENDER_TO_TARGET feature, which can be queried with queryFeature(). Usually, rendering to textures is done in this way:

// create render target
ITexture* target = driver->addRenderTargetTexture(core::dimension2d<u32>(128,128), "rtt1");
 
// ...
 
driver->setRenderTarget(target); // set render target
// .. draw stuff here

texture	New render target. Must be a texture created with IVideoDriver::addRenderTargetTexture(). If set to 0, it sets the previous render target which was set before the last setRenderTarget() call.
clearBackBuffer	Clears the backbuffer of the render target with the color parameter
clearZBuffer	Clears the zBuffer of the rendertarget. Note that because the frame buffer may share the zbuffer with the rendertarget, its zbuffer might be partially cleared too by this.
color	The background color for the render target.

Returns: True if sucessful and false if not.

◆ setTextureCreationFlag()

virtual void irr::video::IVideoDriver::setTextureCreationFlag	(	E_TEXTURE_CREATION_FLAG	flag,

pure virtual

Enables or disables a texture creation flag.

These flags define how textures should be created. By changing this value, you can influence for example the speed of rendering a lot. But please note that the video drivers take this value only as recommendation. It could happen that you enable the ETCF_ALWAYS_16_BIT mode, but the driver still creates 32 bit textures.
